8.3 Interface Information Register
8.4 Interrupt Mask Register
Interface Information Register
Interrupt Mask Register
In Normal Mode, UART’s internal registers can be accessed through nCS and UART’s
GICR (Global Interrupt Control Register) is used for configuring 8 UART channel’s
interrupt mask. GICR is the same register as IPR in this case.
IMR access Option Register through nOPT control signal in MIO mode and GICR access
UART internal Register through nCS or nUART signal. GICR and IMR are same region
and IN16C1058 provides different methods of accessing them.
